The two men exchange pleasantries and a SkyShop catalogue. Their discussion is about the status of the team members, the fact that Gonzalez is MIA and something known as Theta Protocol.

After Ultron: In the present day, Coulson lays it all out for Gonzalez now that the Avengers have averted a global crisis in Sokovia. He suggests that there be one S.H.I.E.L.D. where he acts as director and others serve as his advisers. Gonzalez worries that there is another battle that needs attention closer to home.

Making Mistakes: Raina convinces Jaiying to let her go with Gordon to find the place in her dream. They transport onto the HeliCarrier. Alarms sound as they make their way to cargo area in the lower deck. They find the secret alien substance that was recovered from a dig site a hundred years ago. Hydra had been looking for it, too. A short time later, the idea that Coulson may be repeating Tony's Stark's mistake arises

Masking the Truth: Fitz and Simmons let Agent 33 know that they've removed all parts of the Hydra indoctrination from her brain. That doesn't mean there's still not a little evil inside her. Agent 33 disguises herself as May to get revenge on Bobbi. A brutal fight takes place on a QuinJet. Bobbi gets the upper hand until she's iced by someone else.

Giving Notice: Gonzalez is chosen to be the one to meet with Jaiying at Afterlife. Just before the mission begins, Mack lets Coulson know that he's leaving S.H.I.E.L.D. The reason: He doesn't trust someone with alien blood in him.

A New War: Cal offers to have himself turned over to S.H.I.E.L.D. as a way to protect his family. Skye takes her father to the S.H.I.E.L.D. agents that arrive at Afterlife. Gonzalez meets with Jaiying. He wants to keep track of the enhanced people who may someday try to do harm to others. After hearing this, Jaiying opens up a box which contains a Terrigen crystal which she created. It's harmless to Inhumans, but deadly to all others.
